Benefits of technology

[0007]According to the charged fine particulate water of the present invention, the lifetime of chemically unstable radicals is increased by containing the radicals in the charged fine particulate water having the nanometer particle size, and the diffusion property of the charged fine particulate water into a room is improved. Therefore, bad-odor components adhered to a curtain, clothes and wall surfaces in the room can be effectively deodorized. In addition, it is possible to effectively inactivate bacteria, mold fungus, viruses, and allergens such as pollen, and improve the moisture retention of skin.
[0009]According to this method, it is possible to stably achieve the space, in which the charged fine particulate water having a relatively uniform particle size in the range of 3 to 100 nm is distributed.

Problems solved by technology

However, since the radicals are unstable in the air, so that the lifetime is short, they often disappear before reacting with the bad-odor components.
From this reason, it has been difficult to sufficiently obtain the effect of the radicals.
However, since the charged fine particulate water has a micrometer particle size, it is hard to diffuse in a space.
Therefore, the effect of deodorizing / eliminating the bad-odor components / bacteria adhered to a curtain, clothes and wall surfaces spaced by some distance in a room is not still enough.

examples

[0041]A mist of charged fine particulate water was generated by use of the apparatus shown in FIG. 1A. As the conditions of generating the charged fine particulate water, the first electrode 3 is the negative electrode, the water transfer member 2 is made of a porous material having a porosity of 40%, and a grain size of 3 μm, and a diameter of the needle end of the water transfer member is φ0.25 mm. The electric-field intensity applied between the electrodes is 900 V / mm. By measuring the reduced amount of water in the water tank 1, the generation amount of the charged fine particulate water in this Example is 0.5 g / hr. In addition, since the second electrode 4 is the ground electrode, the polarity of the charged fine particulate water provided from the opening 40 is negative.

[0042]The particle size of the charged fine particulate water was determined by measuring electrical mobility by use of a differential electrical mobility analyzer (DMA / Wyckoff. Co., Ltd), and then converting t...

Abstract

Charged fine particulate water is provided, which has a nanometer particle size, for example, a particle size of 3 to 100 nm, and contains radicals such as hydroxyl radicals and superoxides. This charged fine particulate water can be generated by applying an electric-field intensity of 700 to 1200 V / mm between a pair of electrodes, while supplying water between the electrodes. By allowing the thus obtained charged fine particulate water to diffuse into an indoor space, it is possible to effectively remove bad odor components / bacteria from the indoor space.

Description

CROSS-REFERENCE TO RELEVANT APPLICATIONS[0001]This Application is a U.S. National Stage Application of International Patent Application No. PCT / JP2004 / 007593, filed on May 26, 2004.TECHNICAL FIELD[0002]The present invention relates to charged fine particulate water, and a method of creating an environment where the mist of charged fine particulate water is dispersed.BACKGROUND ART[0003]Japanese Patent Early Publication [kokai] No. 2001-170514 discloses that charged fine particulate water generated by applying electric charges to water is used as an effective dust collector due to the high adsorption property in the air.[0004]On the other hand, it is known that radicals are active chemical species, and excellent in decomposing / deodorizing bad-odor components due to their high chemical reactivity. However, since the radicals are unstable in the air, so that the lifetime is short, they often disappear before reacting with the bad-odor components. From this reason, it has been difficult...
